When I was with APM I learned the phrase “pre-wire.” A pre-wire is simply the meeting before the meeting. As consultants it was important to share the meeting agenda with the customer and be aware of any concerns that they may have. As a manager I still find pre-wires important. For example, we always review the IT Steering Committee agenda with the chairperson a few days in advance of the meeting. The better prepared I am for the pre-wire the better the Steering Committee meeting will go.
Whenever you are trying to get approval for an important decision it is always a good idea to have pre-wire meetings with all of the major decision-makers. Often, just taking the time to meet with meeting attendees in advance is enough to make them sympathetic to your position. A good manager will know the outcome before the meeting ever starts.
